Application filed September 9, '1909. Serial No. 51 ,9%.

To all whom is may concern: l

Beit lrnoivn that I, .Piiiilirn Bowen, a citizen of the United States, residing at Newark, county olf-Essen, State of New Jersey, have invented certain new and use tul linprovements in Sectional lost-Binder Ball-Locks, of which the following is a. speciiication.

This invention relates to improvements in temporary binders or loose sheet holders.

rllhe main objects of this invention are:- First, to provide a temporary binder 'r loose sheet holder which may be very rapidly adjusted to permit the insertion or rcmoval of leaves and sheets, and which, when adjusted, is very secure. Second, to provide an improved temporary binder in which the parts are very simple and economical to produce, and easily assembled, and should occasion require, easily disassembled.

Further objects, and objects relating to structural details, wi ll definitely appear iii-om the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly delined and pointed out in the claims.

A structure embodying the features of myl-Figz l, portions of the post being shown in full line. Fig. 3 is an enlarged detail transverse section, taken on a line corresponding to line 3, Spot Fig. l, parts being shown in. full lines, to better show their relation. Fig. 4t is a detail sectional view taken on a line corres ending to line 4', @et Fig. 3. Fig. 5 is a p an view of one of the clutch blocks, with the clutch lever and spring removed. Fig. 6v is a central section with lever and spring removed. Fig. '7 is a` cross section of the block taken on a line corresponding to line 7, 7 of Fig. 3.

ln the drawings, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends oi the section linesl Referring to the drawing, the structure illustrated is provided with a pair of covers l and 2, to which the clamping bars or meinbers 3 and. l respectively are secured, by rShe clamping' members 3 and 4 are preterably formed et' means of hinged portions 5.

pieces of metal 6, and pieces ot' Wood 7, rigidly secured together, the metal pieces being arranged on the inside ot' the ivo'od pieces. rllie binder posts 8, which are illustrated otl the sectional type, are rigidly secured to the metal piece 6 et one ot the clamping members, the other section ot' the posts being attachlibly secured together by means of screws, as is illustrated. (See Fie..

The metal piece of the clamping niember 3 is provided with holes 9 adapted to receive the posts and the Wood piece is provided with thev chambers l0, which embrace these holes. bese chambers l() are adapted to receive the clutch mechanism for adj istably securing the cover bar or clamping member 3 upon the post' 'this clutch mechanism preferably consis of a block ll, preferably rectangular in shape,l adapted to lit ,into the chamber l0. 'llie block is provided ivitli a hole l2, adapted to receive the pest. fit one side of the .hole 12 is a clutch ball seat 13, which opens on one side into the hole l'tor the post. The inner Wall ot the seat is inclined outwardlyrelative to the post, se that on the outward .movement o t the claniping member the ball draws down, .into clamping engagement .with the post. Tifo release the bar this ball is held in an elevated position, thereby preventing its wedge or clutch ac tion. The block is also brevided with a longitudinal slot lft adapted to receive the lever l5. 'this lever is forked at one end, as 16, to receive the clutch ball 17, so that when the lever is actuated 'on its pivot 18 by pushing on the linger piece 1t) the ball is elevated, thereby preventing its clutch action, and permitting the bar l to be raised upwardly lon the post. A siring 20 is provided for holding the clutch ball normally l in its position, the spring engaging the lever, throwing ,the finger piece upwardly, and thereby throwing the ball downwardly in its seat This spring` is arranged in the slot 14e and is preferably secured by the retaining lugs 2l, which are upset on the block by means ot a punch or the like. The spring is thus supported so that it is impossible `toi' it to become disengaged from the lever 1.5, as it is effectively guided by the Walls of the slot.

The block 1l is retained in the chamber l preferably by means of a retaining escutcheon-lilre plate 22. IThis plate is provided With a hole 23 adapted to receive -the posts, and with a hole 2d adapted to receive the finger piece. (See Figs. 1 and 3.) The plate is preferably retained by means of screws which are threaded into the met-al piece 6 and the clamping bar. The plate 22 also serves as a finishing plate, as itis preferably arranged over the covering 26 for the clamping bars, this covering be ing preferably leather, and formed integral with. the hingedfportions 5, by which the covers l and 2 are connected to the clamp ing bars. When the retaining plate is thus arranged, it covers the edges of the opening formed in the covering above the chamber 10.

By thus forming and arranging the parts, they are very economically produced and can be very easily assembled. 1t Will 4be obvious that the entire clutch mechanism is secured in place by two screws, 25.

In use, the binder may be adjusted to clamp the leaves merely by pressing down upon the clamping bar 3 as the clutch ball seat is shaped so that this movement releases the clutch. VV hen it is desired to release the binder, it isonly necessary to press down upon the finger piece, when the clamping bar can be elevated upon or o'd-from the posts. lt remains in Whatever position it is adjusted to upon the posts, so that the leaves can be readily changed or transposed, as may be. desired.

lWhile the mechanism is economical to produce, it is at the same time very effective ,for

the purpose, and is strong and durable. The

seat for the clutch ball is preferably formed by drilling a hole at an angle to the hole for the binder posts, and so that the seat will open into the hole for the post. The ball actuating lever being forked retains the ball in its seat eiiectively, though this mivht be accomplished by other means. The orked lever is, however, very desirable and advantageous, as it positively carries the bail into and out of its engaging position.

I have illustrated and described my improved binder in detail in the'form preferred by me on account of its structural simplicity, and the convenience with which. the parts may be constructed and assembled, and adjusted When in use. I am, however, aware that it is capable of considerable variation in details. I desire to be understood as claiming my invention broadly as well. as specifically.
